WRENCH.

SPECIFICATION forming part of Letters Patent No. 767,901, dated August16, 1904. Application filed November 13, 1903. Serial No. 181,056. (Nomodel.)

To all whom, it may concern:

Be it known that I, W1LLIAM A. LEFLER, a citizen of the United States,residing at Flint,

in the county of Genesee, State of Michigan,

have invented certain new and useful Improvements in renches; and I dohereby declare the following to be a full, clear, and exact descriptionof the invention, such as will enable others skilled in the art to whichit appertains to make and use the same.

This invention relates to wrenches, and more particularly to that classknown as slidingjaw wrenches, and has for its object to provide a deviceof this nature which will be simple of construction and cheap ofmanufacture and in which the jaws may be quickly and easily adjusted.

In the drawings forming a portion of this specification, and in whichlike numerals'of reference indicate similar parts in the several views,Figure l is a perspective View of the complete device. Fig. 2 is avertical section through the sliding member of the wrench, thecooperating parts being in elevation. Fig. 3 is a view of the forwardedge of the device.

Referring now to the drawings, the present invention comprises the usualstock or handle 5, having ratchet-teeth upon its forward edge and havinga transverse head 7 formed upon one of its ends, one side of which formsa clamping-jaw 8. Slidably disposed upon the stock 5 is a member 9,which carries a second jaw 9. The member 9 has the usual passage 10,with which the stock 5 is engaged, and connecting this passage 10 withthe forward edge of the member 9 is a downwardly-directed diagonal slot11. Disposed within the slot 11 is a triangular block 12, which isprovided with teeth 13 upon its longest edge and lies with these teethin engagement with the teeth 6 of the stock. To hold the block 12 inengagement with the stock, a spring 14 is provided and has one of itsends disposed in a recess 15 in the lower side of the slot 11, theremaining end of the spring bearing against the lower face 12 of theblock, the ends 15 and 16 of the block projecting beyond the sides ofthe slot 11 and are rounded and provided with concavities in their outerfaces to receive the fingers of the operator.

In adjusting the wrench the member 9 may be moved freely in thedirection of the head 7; but movement in the opposite direction will beprevented by the teeth 13 engaging the teeth 6. When it is desired tomove the jaw in this direction, the ends 15 and 16 of the block 12 aregrasped by the operator with the thumb and second finger, respectively,and the block is moved against the action of the spring 1 1 to disengageit from the ratchet 6, when the member 9 may be moved in eitherdirection, as desired.

In practice modifications of the specific construction shown may be madeand any suitable materials and proportions may be used without departingfrom the spirit of the invention.

What is claimed is- 1. A wrench comprising a jaw having a passagetherethrough and an upwardly-directed diagonal slot connecting one ofits edges with the passage, said member also having a jaw projectinglaterally from one of its ends, a stock having ratchet-teeth upon one ofits edges slidably disposed within the passage and having alaterally-projecting jaw upon one of its ends for cooperation with thefirst-named jaw, a toothed block slidably disposed within the slot andlying with its teeth normally in engagement with those of the stock, aspring disposed within the slot and bearing against the block to holdthe latter yieldably in its normal position, the ends of the blockextending outwardly of the slot and adapted for engagement by thefingers of the operator to move the block against the action of thespring.

2. A wrench comprising a member having a passage therethrough and anupwardly-directed slot connecting one of its edges with the passage andcommunicating with the sides of the member, said member having a jawproof the operator to move it against the holding means.

In testimony whereof I aflix my signature in presence of two Witnesses.

WILLIAM A. LEFLER.
